Caratinga Field Report

This report presents the results of an integrated sedimentological, ichnological, stratigraphical and reservoir quality appraisal of the Caratinga Field, Campos Basin, Brazil.

The project investigates the Maastrichtian – Miocene strata, including an interpretation of the gross structural setting, stratigraphic development and sedimentary style of reservoir-scale building blocks together with primary and secondary controls on reservoir quality. A total of 167.64m of detailed core logging has been undertaken together with new biostratigraphical analyses, petrographic analysis including SEM/XRD and conventional core analysis.

The aim of the study is to provide a comprehensive database of analogue data from the Caratinga Field which is of specific relevance to exploration and operating companies assessing the prospectivity and commerciality of existing oil and gas fields and frontier exploration acreage within the Campos Basin. This data has been compiled to be an integral part of the assessment of geotechnical risk for current and future projects in the Campos Basin.
